> By default, Flink creates subdirectories named by UUID (job id) under checkpoint directory for each job. It's a good means to avoid collision. However, it also bring in some effort to remember/find the right directory when recovering from previous checkpoint. According to previous discussion ([Yun Tang's|https://issues.apache.org/jira/browse/FLINK-11789?focusedCommentId=16782314&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16782314] and [Stephan Ewen's|https://issues.apache.org/jira/browse/FLINK-9043?focusedCommentId=16409254&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16409254] ), I think it would be useful to add an option to disable creating the UUID subdirectories under the checkpoint directory. For compatibility considerations, we create the subdirectories by default.
